CISA and NSA issued a joint advisory on BRICKSTORM malware, a sophisticated backdoor targeting VMware ESXi and Windows environments, attributed to PRC state-sponsored actors. BRICKSTORM employs advanced evasion techniques and resilient C2 mechanisms using DNS-over-HTTPS and encrypted WebSocket connections. It allows attackers to manipulate virtual machines and extract credentials. Organizations are urged to upgrade VMware servers, block unauthorized DoH traffic, and enhance monitoring of service accounts to detect this threat.
